NON-REFILLABLE BOTTLE.

To all whom it may concern Be it known that we, GUY P. Cones and PATRICK J. BURKE, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to non-refillable bottles, the object of the invention being to provide a stopper for bottles, embodying a construction which prevents the bottle from being refilled by unscrupulous persons.

One object of the present invention is to provide a sectional stopper, in which the two sections are keyed together, and locked in the neck of the bottle, each of the sections having an annular seating against a corresponding shoulder within the bottle neck.

A further object of the invention is to provide separate and independent chambers or passages, in communication with each other, however, in one of which is arranged a ball check valve, while the other permits the outflow of the liquid or contents of the bottle.

Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, which will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a top plan view of the stopper. Fig. 2 is a bottom plan view of the same. Fig. 3 is a side elevation thereof, showing the spring and key. Fig. 4 is a top plan view of the lower section. Fig. 5 is a bottom plan view of the upper section. Fig. 6 is a diametrical section through the complete stopper and hottle neck. Fig. 7 is a cross section on the line 77 of Fig. 6. Fig. 8 is a detail perspective view of the bottom stopper section.

The stopper contemplated in this invention comprises an upper section 1, and a lower section 2, meeting on the line 8, one of said sections being rabbeted, as shown at 4, to fit within the other section, while adjacent to said rabbeted connection, one of the sections is provided with a projecting key 5, and the other section is provided with a notch 6 to receive said key, thus bringing the two sections of the stopper into proper relation and alinement, and prevent- Specification of Letters Patent.

ing any relative rotative movement of the two sections.

The stopper as a whole comprises a ball check chamber 7 which extends entirely through the lower section and partially but not entirely through the upper section, the upper end of said passage being closed by the top wall 8 which limits the upward movement of the ball or valve 9 arranged to move up and down in said passage. The lower end of said passage is reduced in diameter, as shown at 10, to form a valve seat 11, against which the ball valve rests when in its lowermost position, which it naturally assumes by gravity. The pouring passage, indicated at 12, extends entirely through the upper section of the stopper and partially but not entirely through the bottom section of the stopper, the same terminating in the bottom wall 13. The two passages 7 and 12 are in parallel planes, and are connected by an intervening and communicating air passage 14 to facilitate pouring out the contents of the bottle. The two passages are furthermore in communication with each other at the opposite points 15 and 16, so that the liquid after passing by the check valve 9 may find its way through said oppositely located ports into the pouring-out passage 12, and finally from the bottle.

17 designates a cork or other suitable stopper, fitting into the upper end of the passages 12.

The lower section of the stopper, it will be observed, embodies a central web 15 and extending outwardly in opposite directions from said web are two ball retaining fingers 16 which serve to retain the ball and guide the same back to its seat while preventing the ball from working out of place and becoming caught or jammed so as to render it inoperative.

The bottle is provided interiorly of the neck thereof with twoannular shoulders, 18 designating the upper shoulder, and 1.9 the lower shoulder, while the stopper is provided with an upper annular shoulder 20, at the under side of which is a flexible gasket 21 adapted to be confined between the shoulder 20 and the shoulder 10 of the bot tle. The lower section of the stopper is also provided with an annular shoulder 22, beneath which is a flexible gasket 23 adapted to rest on the shoulder 19 within the bottle. In this way, a liquid and air tight joint is formed at two distantly located points between the stopper and the interior of the bottle neck.

In order to lock the stopper securely in the neck of the bottle, the stopper, under the preferred embodiment of this invention, is provided at diametrically opposite points with upwardly extending spring catches 24:, while the interior of the neck of the bottle is provided with a corresponding annular V-shaped groove 25, terminating in an abrupt shoulder 26, beneath which the free extremities of the spring catches are adapted to snap, as shown in Fig. 6, thus securely locking the stopper in the neck of the bot tle, from which it cannot be removed, except by breaking the bottle.

What is claimed is:

In a non-refillable bottle, a stopper comprising upper and lower abutting sections, the stopper embodying a valve chamber extending through the bottom section and terminating at its upper end in the upper section and also embodying apouring passage extending through the upper section and terminating in the lower section, the lower section embodying a central web and lateral liquid ports leading from the valve chamher to the pouring passage, the upper section embodying an air port leading from the pouring passage to the valve chamber, a ball valve movable by gravity in the valve chamber from the lower section into the upper section and vice versa, and ball re taining and guiding fingers projecting from 35 said central web of the lower section.

In testimony whereof we affix our signa tures in presence of two witnesses.
